Electronic Apparatus and Controlling Method Thereof

2. The electronic apparatus as claimed in claim 1, wherein the processor is further configured to obtain a plurality of powers respectively corresponding to the plurality of noises, and obtain a power having a smallest value from among the plurality of powers as the enduring component of the first time section.

7. The electronic apparatus as claimed in claim 6, wherein the processor is further configured to change the threshold value based on at least one of the first sound, the second sound, the predicted sound, or the noise.

9. The electronic apparatus as claimed in claim 8, wherein the processor is further configured to, based on an enduring component obtained while the third sound is output being less than the threshold value, stop or change processing of the audio signal.

11. The method as claimed in claim 10, wherein the obtaining an enduring component comprises obtaining a plurality of powers respectively corresponding to the plurality of noises, and obtaining a power having a smallest value from among the plurality of powers as the enduring component of the first time section.

16. The method as claimed in claim 15, wherein the obtaining the noise further comprises changing the threshold value based on at least one of the first sound, the second sound, the predicted sound, or the noise.
